When I got this plug now, I have it installed instantly. This worked relatively unproblematic with the accompanying software. (Warning - the software is not included.) Now, about 3 hours after the start, I have to tell you that the water consumption by these plugs noticeably increases. Since we have a toddler in our household, feels this constantly forced to play with this cute monster and also to maintain it. Since this is a water monster, it requires so much and water regularly. However, it needs to do to live well enough oxygen, leading to the constant change of filling level of our sink. I would now like to write here more. However, my son is already in bed and I have promised him to take care of our new monster. I hope that it is not already turned blue - will now make out first for 5 minutes, the water. Until then.
